Tre - The Spreading is developed by two young guys who love the UnrealEditor and want to create a exciting First-Person-Shooter without any zombies, but some aliens and angry animals. A shot overview of the beginnig of the story: You're sitting in your armchair. Suddenly begins your radio to noise. Your TV is also dead and you're wondering what is happening right now. After taking your flashlight and shotgun you want to go to the next village and find out what is going on...though some unidentified flying object cross your way and spread green fog all over the earth. At first only the animals go crazy and attack you, but they're not your biggest problem at all...
This is the intro of "Tre - The Spreading". I'm sorry about the "lighting needs to be rebuild", but it's also displayed after rebuilding everything.
